un raa TES' ALBERT L. GALUSHA, OF SHARON, MASSACHUSETTS.

GAS PRODUCER.

Application filed May28,

To all whom it may concern.

Be it known that I, ALBERT L. GALUSHA, a citizen of the United States of America, residin at Sharon, in the county of Norfolk and tate of Massachusetts, have invented certain new and useful Improvements in Gas Producers, of which the following is a full, clear, and exact description.

In the art of making producer gas, as it is termed, it has heretofore been universally customary to employ some form of apparatus similar in its general construction to an ordinary furnace, and in which provision is made for maintaining a draft up through a rate and a superincumbent mass of fuel. guch forms of apparatus have their practical limitations, for example, it is not possible, orat least practicable, to use very low grade, or very finely divided fuel, the latter because of the difiiculty of maintaining the "draft up through grate and fuel, nor .can such material be employed as will cake under the action of heat and thus solidify the mass of fuel, nor liquid fuel, such as bye product tar without great trouble and expense.

Aside from these limitations the apparatus heretofore used requires much head,

room and space, as there must be ample means and room provided for supplying fuel and withdrawing ash, for p'oking and cleaning the fire, and for other like purposes. All of these well recognized objections have led me to devise and design a form of gas producer of this kind which wholly avoids them.

According to my present invention I dis pense with a grate, and in its place-I use a substantially airtight traveling platform or support for the fuel, in the nature of a belt, which receives at one end of the furnace the fuel in regulatable quantity and carries it through the furnace continuously, and the latter is so constructed as to afford but little head room in the combustion chamber whereby the air or air and steam supplied at one end of the fuel bed may be drawn or forced over the surface only of the fuel, and carries off the unconsumed gaseous products to a. receiver or to any device that may be provided for its immediate use.

The above, in general terms, defines the nature of my improvement, but for practi' cal use certain accessories are required, the nature and purpose of which may best be gathered from the description of the draw- 1920. Serial No. 384,860.

ings illustrating the apparatus which follows:

In these drawings Fig. 1 is a vertical I longitudinal section of the complete apparatus, and

Fig. 2 is a view partly in cross section and 2-2 of Fig. 1. v

The part of the apparatus which may be designated as the furnace is built in any preferred and known manner, preferably and chiefly of fire brick with a brick ceiling 1 and vertical walls 3 overlaid with heat insulating material 4. The'furnace is of substantially greater length than width, and in close proxlmity'to the upper top wall 1 is a traveling belt composed of closely fitting slabs or tiles 5, properly hinged or joined together and supported by two drunis, or sprocket wheels 6 and 7 Immediately under the edges of this belt and secured to the side walls of the furnace are angle irons 8 forming troughs which are filled with coal dust or other finely divided material which not only serves to maintain an air-tight joint between the belt and the side walls, butto lubricate the surface over which the belt travels. 'At one end of the furnace is a shaft 9 carrying outside the furnace wall a sprocket wheel 10 by means of which motion at the proper and desired speed is imparted to the belt 5. At the rear of the structure is a fuel feed pipe 11 through which fuel is 'fed into a compartment 12, sloping towards the bottom under which travelsthe belt. A sliding and adjustable plate 13 is used to regulate the height of the passage into the fur nace and hence the amount of fuel which at any given speed of the belt is carried into the furnace. Alongside this feed compartment is a gas compartment 14 with a delivery pipe 15 and as the gas enters this compartment the ash and impurities have an opportunitygto settle and not pass off through pipe 15 to the scrubber or other devices that may bev used to clean, .store or burn it.

t the forward end of the furnace is a pipe or any number of pipes 16 through which water, steam, tar or other substances may be delivered on to the traveling bed of fuel to promote, retard, or increase the combustion and the eneration of gas. There is also a hinged id 17 that intercepts the dust which may tend to rise from the ash as it is delivered from the fuel bed.

partly in elevation of the same, on the line The manner of using and the mode of operation of this apparatus is as follows: The

fuel to be used is supplied, as explained, to

the compartment 12 and the belt started in motion; When'the fuel has reached the forward end it is ignited by a charcoal fire, gas flame, or otherwise, and'air forced in at the forward end or drawn off from the rear end of the combustion chamber. The heat of this fire volatilizes the fuel in thebed, and as the latter is converted-into gas the belt is set in motion to deliver fresh fuel only so fast as that in the combustion chamber has been converted or consumed. The product, producer gas, passes into the chamber 14 and off by pipe 15, and it will be noted that no air or gas in this product has passed up through the fuel bed, but over it in the combustion chamber of limited capacity.

The, richness of the product may bedetermined by the regulated speed of the belt,

as will be understood by those skilled in the art. If desired the speed of the belt may be such as to produce coke and gas, the

former being delivered from the traveling belt-and falling'into the pitbelow from which it may be readily removed. The entire operation of the apparatus is automatic, and hence its operation-may be conducted at the minimum of expense.

; What I claim as my invention is 1. In a gas producer, the combination with an elongated combustion chamber of limited sectionalcapacity, of animperforate traveling fuel. support traversing the same from end to end,means for depositing fuel thereon at the rear. end in regulable amount, and

-. means for conveying off the'gases which are driven ofi from the fuel bed by the heat developed by the combustion of a portion of.

thefuel at the] forward or delivery end.

2. In a gas producer, the combination with an elongated combustion chamber of limited sectional capacity, of an imperfo'rate or airtight fuel support, means for causing said support to travel through the chamber from end to end ofthe same, means for depositing fuel thereon at the rear end, means for developing and maintaining a high temperature over the top of the fuel bed, and means for conveying off the gases driven ofl' therefromg 3. In a gas producer, the combination with a combustionchamber of limited sectional capacity and substantial length, of a traveling belt traversin the same from end to end and composed 0 heat resisting material and substantially air-tight, constituting a fuel support, I means for depositing fuel thereon in regulable uantity, means for developing and maintaining a high, temperature over the top of the fuel bed, and means for conveying ofi the gases driven ofi' there from by such temperature. I 4, The combination with a combustion chamber of great length but limited height,

of a traveling belt constitutin a fuel supjport and'travers'ing the charm er from end to end, means for introducing substances into the forward end of the chamber for promoting or retarding combustion atthat point, and means for conveyingofl the gases produced by the high temperature due to I such "combustion acting upon the fuel bed.-

v 5, The combination with a combustion" l1" ,chamber of great length butlimited height,-

of a belt movable through the chamber and constituting an-imperforatefuel support, of shelves along the sides .of thechamber and in close proximity to the under surface of the belt for containing a powdered substance to form an air seal.

- 6.'The combination with an elongated I combustion chamber of an infusible fuelfsnpport mounted to travel through said chamber which is imperforate or air-tight, and angle irons secured to the chamber walls under the edges of said belt and containing a suitable material to form an air seal be tween the belt and the chamber walls.

7. The combination with a combustion chamber of.relatively great length and of limited height, of drums or sprockets at its ends, an endless belt of heat resisting material and without air passages mounted on ALBERT L. GALUSHA.
